Abstract

resumo patente de invenção: "bomba de fluxo livre". a presente invenção refere-se a uma bomba de fluxo livre compreendendo um impelidor (11, 22, 33) com uma base de impelidor que é constituída por um lado dianteiro (14, 5, 24) de um corpo de cubo (12, 23) projetando no centro do impelidor (11, 22, 33) e por uma superfície de disco (18, 28) localizada mais profundamente do que o lado dianteiro (14, 24) do corpo de cubo (12, 23) e alcançando uma circunferência externa do impelidor com sua profundidade máxima. a superfície de disco (18, 28) é fornecida com paletas (19, 29, 34) compreendendo lados dianteiros de paleta abertos (20, 30, 35) adjacentes ao corpo de cubo (12, 23) em sua extremidade interna e se estendendo a partir daí para a circunferência externa do impelidor (11, 22, 33). para evitar o acúmulo de material na frente do impelidor (11, 22, 33), é sugerido que pelo menos dentro de um terço interno de seu raio, a base do impelidor não seja localizada mais profundamente com relação à extremidade interna dos lados dianteiros de paleta (20, 30, 35) do que no máximo um sexto da diferença de altura (h) entre a extremidade interna dos lados dianteiros de paleta (20, 30, 35) e a profundidade máxima da superfície de disco (18, 28).patent summary: "free flow pump". The present invention relates to a free flow pump comprising an impeller (11, 22, 33) with an impeller base which is constituted by a front side (14, 5, 24) of a hub body (12, 23 ) projecting in the center of the impeller (11, 22, 33) and by a disk surface (18, 28) located deeper than the front side (14, 24) of the hub body (12, 23) and reaching a circumference. impeller at its maximum depth. the disc surface (18, 28) is provided with pallets (19, 29, 34) comprising open pallet front sides (20, 30, 35) adjacent to the hub body (12, 23) at its inner end and extending from there to the external circumference of the impeller (11, 22, 33). In order to prevent material buildup in front of the impeller (11, 22, 33), it is suggested that at least within an inner third of its radius, the impeller base should not be located more deeply with respect to the inner end of the front sides of (20, 30, 35) than at most one-sixth of the height difference (h) between the inner end of the front sides of the palette (20, 30, 35) and the maximum depth of the disc surface (18, 28) .
